People loved for their beauty and cheerfulness are not loved as irreplaceable, yet people loved for “what their souls are made of” are. Or so literary romance implies; leading philosophical accounts, however, deny the distinction, holding that reasons for love either do not exist or do not include the beloved’s distinguishing features. In this, I argue, they deny an essential species of love. To account for it while preserving the beloved’s irreplaceability, I defend a model of agency on which people (...) can love each other for identities still being created, through a kind of mutual improvisation.
